[0028] A short-circuit connecting component for a transformer secondary circuit terminal block comprises an operating panel 1. A guide groove 2 is provided on one side of the operating panel 1. A connecting component position adjusting mechanism 3 is arranged inside the guide groove 2.

[0029] In this embodiment: Under normal circumstances, the publication number "CN219959654U" discloses a short-circuit connecting component for a transformer secondary circuit terminal block, which is respectively installed in each sliding component through each short-circuit component 34, and prevents the short-circuit component 34 from sliding in the sliding component, and then each sliding component is slidably installed in the guide component, so that the sliding component can slide in the guide component conveniently, and at the same time, the conductive plate 31 in the guide component is fitted with one end of the short-circuit component 34 that passes through the sliding component. When it is necessary to detect the short circuit of the transformer secondary circuit terminal block, the position of each sliding component is adjusted according to the spacing of each detection position on the transformer secondary circuit terminal block, so that the short-circuit components 34 on adjacent sliding components can be conveniently plugged into adjacent detection positions on the transformer secondary circuit terminal block, and then through the added connection component position adjustment mechanism 3, the number of connectors can be conveniently adjusted according to the on-site conditions, and the position of the connector can be conveniently adjusted.

[0030] like Figure 1-Figure 4 As shown,

[0031] Based on the existing transformer secondary circuit terminal block short-circuit connection component, the terminal block short-circuit connection component of the transformer secondary circuit can be solved by adding a connection component position adjustment mechanism 3. This means that once the terminal block is installed, the number of its connectors cannot be adjusted. When the circuit system needs to be expanded or modified, the fixed number of connectors may not meet the new design requirements. In addition, if some connectors are not used, they may occupy valuable space or become potential failure points.

[0032] More specifically:

[0033] In combination with the above content, in order to conveniently adjust the number of connecting parts according to the situation on site and to facilitate the position adjustment of the connecting parts, a connecting part position adjustment mechanism 3 is arranged inside the guide groove 2, and the connecting part position adjustment mechanism 3 includes a conductive plate 31, a sliding card plate 32, a sliding side plate 33, a short-circuit component 34 and an assembly component 35. The conductive plate 31 is fixedly connected to the inner side of the guide groove 2, the sliding card plate 32 is slidably connected to the conductive plate 31, the sliding side plate 33 is slidably connected to one side of the operating panel 1, and the inner wall of the sliding side plate 33 is fixedly connected to the end of the sliding card plate 32, the short-circuit component 34 is arranged on the outer wall of the sliding side plate 33, and the assembly component 35 is arranged on the operating panel 1 and connected to the sliding side plate 33.

[0034] In this embodiment: before the short-circuit detection of the substation secondary circuit terminal block is required, the number of sliding side plates 33 can be conveniently adjusted through the assembly component 35, and because the conductive plate 31 is fixedly connected to the inner side of the guide groove 2, the sliding card plate 32 is slidably clamped on the conductive plate 31, the sliding side plate 33 is slidably clamped on one side of the operating panel 1, and the inner wall of the sliding side plate 33 is fixedly connected to the end of the sliding card plate 32, the short-circuit component 34 is arranged on the outer wall of the sliding side plate 33, and the assembly component 35 is arranged on the operating panel 1 and connected to the sliding side plate 33. After the quantity adjustment is completed, through the short-circuit component 34, since one end of the short-circuit component 34 is connected to the conductive plate 31, the adjacent detection positions on the adjacent substation secondary circuit terminal block can be short-circuited, which is convenient for the staff to conduct subsequent detection, and the position of the short-circuit component 34 can be conveniently adjusted. Therefore, the short-circuit component 34 with adjustable position makes the configuration of the secondary circuit more flexible and can adapt to different operation and testing requirements, especially during the upgrade, transformation or maintenance of the substation.

[0035] Specifically, the short-circuit assembly 34 includes a guide arm 341 and a connecting pressing plate 342 , wherein one end of the guide arm 341 is fixedly connected to the outer wall of the sliding side plate 33 , and one end of the connecting pressing plate 342 passes through the other end of the guide arm 341 and is connected to the side wall of the conductive plate 31 .

[0036] In the present embodiment: in order to ensure a more stable connection with the conductive plate 31, one end of the guide arm 341 is fixedly connected to the outer wall of the sliding side plate 33, and one end of the connecting pressing plate 342 passes through the other end of the guide arm 341 and is connected by contact with the side wall of the conductive plate 31, thereby facilitating the connection of the line through the connecting pressing plate 342. At the same time, the structural stability of the connecting pressing plate 342 can be ensured by the guide arm 341.

[0037] To be more specific: the assembly component 35 includes a sealing block 351, a fixing bolt 352, a guide plate 353 and a threaded sleeve 354. A limiting groove 12 is symmetrically opened on one side of the operating panel 1 relative to the two sides of the guide groove 2. The guide plate 353 is symmetrically slidably clamped on both sides of the inner wall of the limiting groove 12, and the outer wall of the threaded sleeve 354 is fixedly connected to the end of the guide plate 353. The sealing block 351 is clamped on the end of the limiting groove 12, and the fixing bolt 352 is installed on the sealing block 351.

[0038] Further, such as Figure 1 As shown, a limiting bolt 331 matching the threaded sleeve plate 354 is installed on the sliding side plate 33 .

[0039] The locking cam 352 is fixed to the locking cam 353 to lock the locking cam 354. The locking cam 353 is fixed to the locking cam 354 to lock the locking cam 354.

[0040] It can be understood that the end of the limiting groove 12 passes through the end of the operating panel 1 , and the other side of the operating panel 1 is fixedly connected with the handle 11 .
